Rex Ryan thinks there is a chance Mark Sanchez might not play on Sunday.

“He has a sore shoulder, there is no doubt about it,” Ryan said. “(Trainer) John Mellody said he wouldn’t have been able to [play a game] yesterday. He threw the ball today. He didn’t have a ton of zip on it. This one could be a game-time decision. I feel comfortable with Mark Brunell. This is the best he’s felt all year.
